Blog readers who grew up in the Chicago area during the 1960s and 1970s will recognize these two characters. It's BOZO (Bob Bell) and OLIVER O. OLIVER (Ray Rayner) from WGN-TV's, BOZO's CIRCUS. This 1971 photo was taken either during the Grand Prize Game or the end-of-the-show's audience participation game. The prize shown is Remco's BOATNIKS. Thanks to fellow classic Chicago kids TV fan and cartoonist, MARK CHRISTIANSEN, for sending this over.
